Two critically endangered Limon harlequin frogs (Atelopus sp. spumarius complex) in amplexus at Centro Jambatu in Quito, Ecuador. These two animals were originally from San Carlos de Limón, Morona Santiago Province, Ecuador. The captive breeding program has been successful in Centro Jambatu, saving the species from the extinction. The natural habitat of this species faces numerous obstacles, including loss due to mining, deforestation road constructions and farming activities.

Brown color morph of the endangered Limosa harlequin frog (Atelopus limosus) at the Panama Amphibian Rescue and Conservation Project. This is a project designed to establish captive breeding populations of frogs at risk of extinction from the frog-killing Chryttrid fungus. This species is highly susceptible to the fungus and has declined through most of its range in central Panama, where it is endemic. This is the brown color form. It’s now extremely rare to see one in the wild.
